DESIGNATOR FOR PNEUMATICI? CARRERS.

Application filed August 18, 1925.

This invention pertains to carriers employed in pneumatic dispatch systems and more particularly to group designators for such carriers useful for purposes of ready classification. Such group designators are particularly useful in making a primary division into groups of all of the carriers in the system by causing one group to present a different appearance from any angle of view from carriers belonging to other groups, it being understood that any usual designating means, for example, numerals or letters are or may be provided for d istinguishing individual carriers of a group.

The principal object of the present invention is to provide means readily applicable to a carrier of any usual type but particularly to a carrier having non-removable heads, for example, a so-called take-apart carrier, which will distinguish that carrier from another carrier not belonging to its group. A. secondary object is to provide a designator of durable and inexpensive character', lightJ in weight, and of material obtainable in a variety of brilliant and permanent colors.

In the accompanying drawings, in which a preferred embodiment of the invention is illustrated by way of example,-

Fig. 1 is a side elevation of a take-apart carrier embodying the present invention;

Fig. 2 is a side elevation of the same carrier with its inner and outer shells separated and axially aligned, and with my novel designator device interposed between them;

Fig. 3 is a bottom plan view of the designator device shown in Fig. 2,;

Fig. 4; is a fragmentary diametral section through the upper end of the lower carrier shell shown in Fig. 2, with the dcsignator ring applied thereto;

Fig. 5 is a fragmentary side elevation to small scale showing the invention embodied in a message carrier of well-known type;

rif;

Fig. 6 is a view similar to Fig. 5 but show- Serial- No. 50,936.

The outer shell 3 is also provided with a head 4 non-removably secured to one end and is provided with the usual driving washer 5 adapted to make air-tight contact with the inner surface 0f the pneumatic transmission tube.

The inner shell 1 is furnished with an elongate access opening 6 which is adapted to register with a corresponding access opening 7 in the outer shell when the shells are turned to the proper relative angular position.

an axially directed channel 8 extending out- Wardly from the opening 6 to the end of the shell. This channel may conveniently be formed by pressing the metal of the shell inwardly during the process of manufacture. The channel 8 forms a passage for the head of a stop pin 9 projecting inwardly from the wall of the outer shell 3 near the head end of the latter. `When the parts are assembled the head of this stop pin 9 engages the edge 10 of the aperture 6 of the inner shell and thus prevents relative axial movement of the shells except when the shells are so relatively positioned that the head of the pin may move axially along the channel 8.

Preferably the inner endof theopening 6 is widened out atl each side to form recesses 11 and 1:2 respectively for the reception of the pin 9 so that the shells may be turned in one direction to bring the apertures G and 7 into enact registry or in the opposite direction completely to close the carrier.

Preferably the outer shell is provided with an opening 13 in its wall which may be surrounded by an outwardly projecting raised flange 14, thus providing a pocket for the reception. of an index slip 15 of the usual n character. This slip may be inserted within the pocket when the shells are separated and is retained in position by engagement with the outer surface of the inner shell.

in accordance with the present invention T provide designator ring 16 which is adapted to lit over the open end of the outer shell 23 as indicated in Fig. e. This ring 16 is circumferentially continuous and of distinctive external appearance. For example i.. may have a distinctive color or surface pattern. When color is relied upon to give the distinct-ive appearance T .find that celluloid is a desirable material from which to malte the ring since it can be colored very The end 7 of the shell 1 is provided with i readily, is light in weight, tough and durable, and may readily be given the desired shape and size.

rlhis designator ring while iitting snugly over the end` of the shell 3 is readily removable when the shells are separated so that it worn or broken it may be replaced 0r when desired it may be interchanged -for a. ring ot' another color or appearance.

To hold the designator ring closely adjacent to one of the heads of the carrier so that the head may torni a protective overhanging flange for the ring, and so that the ring may not interfere with the access openings, I provide stop means to prevent axial movenient of the ring relatively to thc body of the carrier. A convenient way of 'forming suitable stop means consists in turning in the edge ot the ring to provide a radially direc-ted flange 17. rlhis flange bears agains the outer end 18 of the shell 3 and is clamped between the edge 1S ot the shell and the overhanging head 2 of the inner shell so that axial movement ot the ring is prevented.

As the inner shell l must telescope wit-hin the outer shell 3, it is essential that the 'flange 17 be no wider in a radial direction than the thickness of the shell 3 and I pretcr to malte this flange slightly less than the limiting width in order that the opening ll) defined by the inner edge of the flange may be of suiiicient diameter to permit ready entry ot the inner shell without sp-ecial care upon the part of the user.

llhile I have shown the designator ring as applied to the outer shell, I contemplate that under some circumstances it might possibly be applied to the inner shell, the outer shell being cut away to receive it and expose it to view. Under such circumstances it might be necessary to constrict the open end o'l.' the inner shell to afford space 'for the reception of the designator ring.

In Fig. 5 I have shown the present invention applied to a message carrier oi usual type, this message carrier comprising tubular body portion 2O provided at one end with the flaring skirt 2l and at its other with the head 22 having the driving washer 23.

rI`he carrier is provided with the usual rotary selecting ring 24 having an opening 25 to exhibit a selected distinguishing numeral upon the outer surface of the carrer shell. In this case my improved designator ring 16 is fitted snugly about the ring 24, the narrow inwardly directed radial flange 17 of the ring 16 engaging the edge ot the ring 24, such flange being substantially no wider radially than the thickness of the ring 24:. In this case the ring 16 is furnished with an opening 27 registering with the opening` 25 so that the numerals upon the body of the carrier may be exhibited.

Fig. (l a carrier ot the saine type is shown, but in this case the designator ring 16, while being mounted on the ring 24, is arranged in reverse relation as compared with that shown in Fig. 5. That is to say, in the latter .figure the designator ring 16 is adjacent to the carrier head, while in Fig. 6 the designator ring 1G is spaced irom the head. This latter arrangement is permitted by the fact that the radial flange l? is no thicker than the thiol-mess ot the ring 2l so that the composite rin comprising the parts 1G and 2lcan readily be slipped lengthwise oit the carrier body.

In Fig. 7 I have shown carrier of ordinary type, for example a cash carrier, having a body portion 25. a head 2G, and my improve-d dcsignator ring 16 encircling the body 25 at a point closely adjacent to the head.. In this case the radial riant/je lits within the angle between the end ot the carrier body and the tace of the head and thus prevents axial movement of the ring 'ld 1While t-he inwardly dire ted li' is desirable in most cases, I conten'iplate that sach tiangc may be dispensed with it' other and eqn' aient means be provided t'or sccurely attaching the ring to the carrier body or other part with which it is associated. For example such an annulus or ring unprovided with a ilange, may be cen'iented or riveted in place or may merely be made of a diameter such that when 'forced over the cylindrical carrier part with which it is associated its trictional engagement therewith is sullicient to prevent displacement.

I claim:

l. A designator device for a take-apart pneumatic carrier having a body portion consisting of separable, telescoping cylindrical shells, each provided with a non-removable head, said designator comprising a continuous removable ring o'l colored Celluloid fitting over the open end of the outer shell and having a radial stop member engaging the edge of the shell, said stop member being arranged to permit tree telescoping ot the shells relatively to 'one another.

2. In combination with a pneumatic despatch carrier having a body portion comprising concenctric relatively rotatable telescoping cylindrical shells longitudinally separable in one position of relative angular adjustment, each shell having a non-removable head, a continuous ring of distinctive appearance encircling the body portion of the carrier at a point closely adjacent to one o1c the xed heads, said ring being provided with means tor preventing longitudinal movement thereof relatively to the body portion ot the carrier when the parts of the latter are assembled, said ring being removable from the carrier when the shells are separated.
